For the left hand, ee recommended the root of the chord for beat one
and the third note of the chord for beat three. For example, on a
G chord that would be a G on beat one, then a (normally lower) D on
beat three. And interspersed on beats two and four in the right
hand would be a G triad, in whatever form you can reach (closed for me:
I have small hands) and in whatever inversion is convenient or
esthetically pleasing.
